Answer:
2k-3
Step-by-step explanation:
the square of k is k times k so 2k (two times k) and less than three means minus three.
Answer:
103
Step-by-step explanation:
93 + 5 + 5 = 103
Answer
-7r2+12r-8
Step-by-step explanation:
Alright, so in order to find this, you will nee to use the Triangle Inequality Theorem.
We’ll make the values = to variables to make it easier. a=1 b=1 c=2
All of the inequities need to be true.
a+b>c
b+c>a
c+a>b
Now replace the variables.
1+1>2 2>2 (False)
1+2>1 3>1 (True)
1+2>1 3>1 (True)
Since one is false, 1,1, and 2 cannot make a triangle.
Answer:
972π or 3052.08 if π=3.14(remember to label the answer with your units)
Step-by-step explanation:
The formula for the volume of a sphere is 
π
. So, just plug the radius into the formula. <em> </em>in this case is 
which is 729. For, 
×729, the 3 and 729 cancel out to create 4×243 which is 972. Just add π to this and you get 972π. If π is 3.14 just multiple 972 and 3.14 to get 3052.08.
